Hi Everyone,
I have a problem with Port Forwarding.
I have a Huawey USB modem connected to my TP-LINK Router TL-MR3420 and I need to access a PC I have home from the internet.
I've created the port forwarding rule to the correct port on the PC, but I'm not able to access my PC.

Can someone help me here


Thanks a Lot

WAN IP is private or public?
private IP range:10.0.0.0—10.255.255.255; 172.16.0.0—172.31.255.255; 192.168.0.0—192.168.255.255
If it is private, you have to contact your ISP and confirm if you can obtain a public IP.

Ok, here the list of IP's:

3G/4G Provider IP: 113.52.112.9 (CTM Macau)
USB Huawei E303 IP: 192.168.8.1
TP-LINK Router IP: 192.168.0.1

What do I have to do?

Which port did you open for your PC?
Can you access it locally with http://LAN IP: port?
Check IP settings on your PC. Is it static or dynamic?

I have the PC running with static IP Address (192.168.1.30) and created the ports I need on the Router regarding the service I use.
One example is Port 80. The Router port 3080 points to the PC port 80.

Yes I can access http://192.168.1.30

Does any one know if TP-Link has any plans to fix the port forwarding on 3/4G issue?

Did you read the thread I sent? I don't think there is a problem with port forwarding on the router itself.
